Someone who can't help but to fuck up whether they are natural at it or just an ass. Sometimes it's unsuspecting. It also can just be someone who fucks up by saying the wrong thing. A Fuck Up can either be a good person who is pretty damn accident prone by default or just a dipshit.
The following is A Fuck Up who says stupid things:
Donna: I love you.
Eric: I love... cake.

Get the A Fuck Up mug.
A level of status. Typically used in reference to being physically, mentally, morally/ asthetically, performance-wise, or even theoretically damaged in some way. It, in and of itself has many gradient levels, such as 'slightly fucked up', or 'extremely fucked up', but all versions have to do with describing the level of damage. A wonderfully universal root word, to be sure.
1. (physical): "Ow! Man, I just fucked up my thumb by slamming it with my hammer!"
2. (mentally): "That chick is SO fucked up, she ate a full ounce of magic mushrooms!"
3. (morally/ asthetically): "See that landscaping feature? Now THAT is fucked up! Anyone with half a brain wouldn't do that!"
4. (performance-wise): "This horse's lap time is so fucked up, I could wak around the track faster than him!"
5. (theoretically): "Naw, man...that would be so fucked up if you did that!"
